Debug Info: Move isSubprogramContext from DebugInfo to DwarfDebug.

This helper function needs the type identifier map when we switch
DIType::getContext to return DIScopeRef instead of DIScope.

Since isSubprogramContext is used by DwarfDebug only, We move it to DwarfDebug
to have easy access to the map.
